上海地铁车厢热舒适调查研究与分析

Thermal Comfort Investigation and Analysis on Coaches of Shanghai Metro

通过对上海地铁九号线车厢内热环境进行现场测试和问卷调查,将车厢内的热环境的PMV-PPD指标与RWI或HDR指标进行对比分析,以及车厢内MTS平均热感觉投票的线性回归,研究车厢内环境在夏季、冬季以及过渡季节的热舒适,发现冬季以及过渡季节车厢环境存在较高的不满意率,相关指标与实际测试存在较大的差别,而夏季的车厢热舒适明显偏冷。

Through the measurement of several parameters and questionnaire survey,the PMV and PPD indices on the coach was calculated.Considering their application limits,the RWI and HDR indices was used as a contrast.To the question that the temperature on the coach deviates from the comfort range seriously,a liner regression was carried through MTS to get the thermal neutral temperature.The study on the coach shows that the percentage of unsatisfied of the thermal environment is high in winter and transition seasons,but the results revealed by those indices vary greatly,and the temperature in summer is apparently lower than that passengers feel comfort.
